Title: Hinge pin for motor vehicle doors - has helical grooves filled with plastics used as lubricant
Inventor: KNUEDEL GUENTER
IPC: E05D9/00
Filed: 1974-02-16
Abstract: The hinge pin with plastics filled grooves can accommodate high loads and it can be assembled by automatic machines into hinge components. The plastics material acts as a lubricant for the hinge pin. The metal pin has a section with helical grooves of small pitch. These grooves are filled with plastics material and the plastics filling and the metallic crests of rounded threads come into contact with the hinge sleeve. The main part of the pin has helical grooves with much larger pitch and these grooves are also filled with plastics material. The plastics material adheres firmly to the groove and hence an integral unit is formed which can be handled in automatic assembly machines.

Title: Protection cct. for line output-stage transistor in TV receiver - has resistor carrying transistors current and diode limiting current
Inventor: DAUTE OTTO
IPC: H03K4/08
Filed: 1974-02-19
Abstract: The protection circuit, for the line output stage's transistor in a television receiver, has a resistor coupled between the positive supply and the output stage transistor so that the latter's current passes through the resistor. A diode is connected between the transistor-end of the resistor and a d.c. voltage such that the diode conducts for values of transistor current up to the max. and is reverse-biassed for currents, i.e. excess currents, above this max. The d.c. voltage is derived from an additional transformer-winding by a diode and a capacitor. The resistor does not increase the inner resistance of the supply voltage to an unacceptable level.

Title: Moving magnet device for transferring energy - has non-magnetic pieces rising and falling periodically screening magnet drive field
Inventor: MAU HORST
IPC: H02K53/00
Filed: 1974-02-26
Abstract: The moving magnet device, for transferring energy has stationary magnetic poles facing a moving pole system. The pole system is attracted by the stationary north pole until it strikes an end-stop, whereupon the lifting mechanism comes into operation. The lifting mechanism controls two non-magnetic pieces attached to the ends of a cord. One piece is raised up when the end-stop is reached and the other piece falls. The south pole then attracts the magnetic system and the piece that was up now falls when the opposite end-stop is reached. The whole thing continues operating in this way.

Title: Impurity concn. adjustment in semiconductor device - involves cutting wafers from bar of lower concn. and then diffusion of additional dopant
Inventor: BURTSCHER JOACHIM DIPL ING DR
IPC: C30B31/18
Filed: 1974-03-19
Abstract: The basic doping, i.e. the doping present before the pn-junction is produced in a semiconductor device can be set by cutting a wafer from a crucible- or zone-pulled semi-conductor bar which has an impurity concn. below the required value. Additional dopant is then diffused in until the desired figure is reached at the rim. The impurity concn. of the bar is chosen such that the lateral inhomogeneities lie below a desired threshold. This prevents striations and other impurity fluctuations in semiconductor bars from having a detrimental effect on the quality of the semi-conductor device.
